METAL anno No Brewing.

My invention appertains generally to new and useful improvements in metal alloys and more particularly to an improved metal altoy for use in preparing or melting down a certain metals or combination of metals.

The primary object of my invention is the production of a metal alloy intended primarily for use as a deoxidizing and fluxing agent in the preparation or melting down IE of certain metals or combination of metals.

Another very important object of my invention is the production of an improved metal alloy which will also act as a scavenger or cleanser, and by the use of which W it is possible to produce metals of maximum strength, density and ductility.

A further object of my invention is the production of such a metal alloy composed of a plurality of ingredients, all of which may be readily obtained and which ingredients can be easily compounded.

My composition consists generally of a mixture of nickel, tin, manganese, phosphorus and copper.

In preparing my composition, I prefer to use the above ingredients in about the following proportions viz:

Nickel 40% to 50%, tin 3% to 10%, phosphorus /100% to 1%, manganese 1.50%

Application filed April 20, 1826. Serial No. 103,387.

to 5%. Copperthe amount of copper used being the amount necessary to form 100%.

As seen from the above, the proportions of the ingredients can be somewhat varied as may be found desirable. The alloy may be used in varying percentages as an addition to other metals for the purposes above named, or may be used as a'whole to produce castings for various purposes.

By the use of my improved alloy, it is possible, by theouse of small percentages, 40 to obtain a superior casting with a dense fine grain, with increased tensile strength, improved machining qualities, and which will hold in suspension a high percentage of lead without sweating out when cooling.

The alloy can also be used to great advantage in bronzes and red brass, as a deoxidizer and strengthener and to further improve the machining and wearing qualities of the same.

What is claimed is:

A scavenging alloy consisting of 40 to nickel, 3 to 10% tin,-30/100 to 1% phosphorus, 1 and 50/100% to 5% manganese and the balance copper to complete In testimony whereof I aifix my signature.
